To think the reality of online selling is far worse than people suggest on here...

I’ve sold appliances, furniture etc on gumtree for about half of their original value. Vinted is good for small things - I work about 500m from a post office so I don’t mind packaging and dropping things off for £2/£3 a time - I made £350 last year on Vinted and I’m at £110 this year so far. Most I’ve ever sold anything for is about a fiver, it just all adds up. My DH is prone to hoarding though so I’m constantly finding things to declutter and sell! Other people I know have done well on Facebook marketplace but I find things take ages to sell on there and often go for lower than what you would like.

I think it depends on where you live. I think if you live in an affluent area there is not much uptake for 2nd hand items as people can just buy what they want new without too much pain.

Secondly, I think timing is everything. I had gorgeous new / like new summer dresses my DD had outgrown. Posted with clear pics - total bargain - £2 each etc. Didnt sell for ages so I took the listing down. Reposted just before the summer school hols with a higher price and all gone in a day.

Supply vs demand plus timing plus luck.

I think when people say it sold for 80/90% of what they paid for it they didn't buy it new. Things likes kids bikes hold their second hand value well.

I think that if someone can afford £150 for a second hand pushchair, they'll just buy new.
Understand that yours is fancy and a bargain...but I still imagine the mindset is to buy unused.

Having said that, my friend sold a second hand sofa at £250. I had thought she was tripping as the sofa itself was nice but not immaculate. Lo and behold someone paid it!
I was astonished.

I buy and sell my son's bikes on Gumtree and eBay - he rides Islabikes and they always sell instantly for about what I paid for them. On eBay you can check the sold prices and see that both Islabikes and Frog bikes sell at good prices.

I think the sites you are using don't have enough people on them.

In my (limited) experience, it's all down to luck. I recently sold a lot of children's toys we no longer needed, including 3 bikes. These were not new by any stretch but in good condition. I sold all of them - the one that was the cheapest to buy originally sold for around 50% of what we paid. The other two, for about a 5th. I was happy though as they were bought years ago and I was as much interested in knowing they had a new owner as in the actual money.

When I sold baby stuff ages ago at a sale, I got about 30 to 50% of the price despite the fact they were barely used.

I wouldn't expect to get near full price even if I had a new, never used item, as why would a complete stranger buy something second hand when they could get a brand new one from the manufacturer, possibly with guarantees etc, for near to the actual price?

Small items on ebay that you can post sell reasonably well, if it's items that have to be collected you have a very limited number of potential buyers.

Absolutely depends on where you live and what the 'online selling' culture is like locally. I lived in a city where the local middle-class family area would have things snapped up at reasonable prices (ie not dirt cheap) in 'private' facebook groups.
In a smaller town, things generally sell but people put them on for much lower so that's the 'accepted' level.

That said I've never seen anything for for 80%/90% of the price unless it's rare and literally unused. No-one is going to pay 90% for something that's second-hand when they could get new and returnable for not much more.

"Travel systems" are hard because they are many specific items together and you might only want one or two of those.

Coffee tables are down to individual taste and not something you tend to buy/change regularly so unlikely that someone is looking for your specific table in the time window you're selling it.

Frog and Isla bikes usually sell well in the well-off areas. I've never bothered paying a premium for those, though.

I've given up trying to sell things. I worked out that the last time I tried I ended up getting about £5 a hour by the time I'd factored in all the time spent listing, dealing with BS etc and it just wasn't worth it. I donate everything to charity, and consider it a large charitable donation. I stopped my charity direct debits in lieu. So much less stress and the charities make much more than my direct debits came to.

I think it is harder than it used to be. I used to have the occasional browse of Gumtree (as a buyer) and sometimes picked up good quality items that I just happened to spot.

But that site is drowning in rubbish now. It’s impossible to browse. Things like 20 year old PC games priced at £30. Pages and pages of old clothes, homemade items, random bric a brac, electrical parts, everything constantly reposted when it doesn’t sell. Things that I assume have fallen off the back of a lorry.

I don’t bother even looking anymore. I don’t have time to wade through pages and pages of rubbish on the off-chance of finding something worthwhile. I assume Facebook marketplace is the same. Everyone is trying to sell, nobody who wants to buy anything can see the wood for the trees.

Have you tried a local mums Facebook group?

I had a load of baby stuff that never sold on marketplace, but as soon as I posted it on "Town Local Mums" I had people fighting over it and paying good prices.

It really depends but I have had fairly good luck with selling second hand

Sorry cross post!

It depends where you live. I have sold items in the past for what I paid for them new. Not since I moved to a different area. If you are in the SE I thnk a lot of people wouldn't have ANY spare cash even though you would think something like a frog bike would sell well.

Have you tried the frog bike resale pages on facebook?

I'd love an oak coffee table but I can't travel!

I think it depends where you are trying to sell. Facebook marketplace is full of time wasters, so you won't sell anything at reasonable money on there, and ebay fees are extortionate.

I have reverted to good old fashioned car boot sales. I am not alone it seems.
